What is coagulation function? Does tooth extraction have to do coagulation function test

You may be asked to do blood coagulation function test when tooth extraction. Many people say they don't understand. It's just tooth extraction. Is it necessary to do blood coagulation function test? Let's introduce what is blood coagulation function test and whether it is necessary to do blood coagulation function test after tooth extraction.

What is coagulation function

Coagulation function, literally, is the function of blood coagulation and coagulation. In medicine, it is defined as an ability to turn blood from a flowing liquid state to a gel state that can not flow. In essence, it is the function of transforming soluble fibrinogen into insoluble fibrin in plasma, and it is an important link in human physiological hemostasis. Whether people's coagulation function is normal or not is related to the wound healing

Indicators of coagulation function

The main indicators of coagulation routine screening are as follows: prothrombin time, fibrinogen quantification, activated partial thromboplastin time, thrombin time.

How to see coagulation function examination index

If prothrombin time is prolonged for more than 3 seconds, it indicates that there may be liver parenchymal injury, vitamin K deficiency, disseminated intravascular coagulation, etc.; if prothrombin time is shortened, it indicates that the blood is likely to be in hypercoagulable state or thrombotic diseases, such as myocardial infarction, cerebral thrombosis, deep vein thrombosis, etc.

If the activated partial thromboplastin time is prolonged for more than 10 seconds, lupus anticoagulants, heparin like substances and factor VIII antibodies can be seen in hemophilia and blood circulation; if the activated partial thromboplastin time is shortened, it indicates hypercoagulable state or thrombotic disease.

Fibrinogen quantification mainly reflects the content of fibrinogen in plasma. Severe liver cirrhosis, DIC, congenital hypofibrinogenemia and other diseases can reduce fibrinogen, on the contrary, in the case of severe tissue damage and malignant tumor, fibrinogen will increase.

Thrombin time mainly reflects the time of fibrinogen to fibrin. If it is prolonged for more than 3 seconds, it may indicate liver disease, heparin like anticoagulant substance increase, systemic lupus erythematosus, etc. if it is lower than the standard value, it is generally regarded as having no clinical significance.

Is it necessary to do coagulation function test for tooth extraction

The indicators of coagulation function test reflect the self hemostatic ability of the human body in the case of bleeding, which is very necessary in tooth extraction, because although tooth extraction seems to be a simple treatment, it will inevitably cause bleeding. Through the blood coagulation function examination, it is convenient for doctors to understand the hemostasis and blood coagulation function of patients, formulate more suitable treatment plan, and try to avoid the unexpected phenomenon that may appear in the operation.

The above is a small series to introduce to you whether the extraction of blood coagulation function test related content, through the above we know, extraction of blood coagulation function test is very necessary. I hope you respect and follow the doctor's instructions. Well, that's all for today. Thank you for reading.
